CAROL VORDERMAN has taken to Twitter to discuss the heartbreaking moment guests said a final goodbye to Professor Stephen Hawking yesterday, after attending the memorial service at Westminster Abbey in London.

Carol Vorderman was joined by her daughter Katie King at London’s Westminster Abbey to say goodbye to the late great scientist Stephen Hawking yesterday.

Following the interment, the former Countdown star has let her 388,000 Twitter followers in on an emotional moment which happened shortly after the memorial service.

In a series of posts, the 52-year-old opened up about how Lucy Hawking, the daughter of the professor, paid tribute to her late father - who died at the age of 76 on March 14 earlier this year.

Carol revealed the author, 47, stood on a stage in front of guests to make a moving speech about the late physicist.

Writing on Twitter, the TV presenter told fans: “Lucy Hawking (Stephen's daughter) stood on a little stage and said… ‘I have travelled the world with my father many times, and I have introduced him onto a stage hundreds of times, I've even introduced him in the form of a hologram.’

The mathematician went on to suggest her followers took some time to listen to the piece, in a place where they wouldn’t be distracted.

She wrote: “If you can find the piece online by Vangelis, which was also beamed from @esa into deep space, then please listen with no distractions, it will change how you think and what you do .... with love #StephenHawking.”
